This sounds like a common issue with Camunda 8 Docker deployments where forms appear blank due to various configuration or data export problems. I found the following relevant resources:
- User Task Not Visible in Task List - covers Tasklist V2 mode issues in 8.8+
- Migrate to Camunda user tasks troubleshooting - embedded vs linked forms issues
- Process deployed, but not listed on operate ui - Zeebe export pipeline problems
- Task Forms not showing data after update - post-upgrade form data loss
- Tasklist UI mode configuration - switching between V1/V2 modes
- Form linking - Camunda Form (linked) - known bugs in 8.4.0-8.4.2
Does this help? If not, can anyone from the community jump in?
